INFORMATION ABOUT BIOTOPE
关于生物群落的信息

Description of the area surrounding the biotope: The river Metapa is a stream that is found in the department of Escuintla, Guatemala. It sits at an altitude of 71 meters above sea level at 14°10’60” N y 90°42’0″ W. The river flows next to the river Michatoya and they both come together further downstream. By the river Metapa, you can observe two types of predominant habitats. One is the green riverside composed of diverse grasses and small trees which grow just at the edge of the river, these trees are responsible for the leaves and the logs that can be seen floating downriver. While the second is a habitat which is composed of rocks, stones, and sand of different granulometry. You can find large rocks sitting on the edge of the river and in these areas the water has better fluidity and visibility. This area of the Metapa river was the one used for the biotope aquarium.
生境周边区域描述：梅塔帕河是位于危地马拉埃斯昆特拉省的一条溪流，地处北纬 14°10′60″、西经 90°42′0″，海拔 71 米。该河流与米查托亚河并行流淌，并在下游汇合。沿梅塔帕河可观察到两种主要生境类型：其一为绿色河岸带，由多种草本植物和小型树木组成，这些树木紧邻河岸生长，其落叶和倒木常可见于河中随波漂流；其二为由不同粒径的岩石、石块和沙子构成的生境。大型岩石坐落於河岸边缘，在这些区域水流更为通畅，能见度也更高。本次生物缸所模拟的正是梅塔帕河的这一区域。

Description of the underwater landscape of the biotope: The river flows across areas of large round rocks found on the margin of both sides of the river while at the edge of the river you can find rocks and round stones of dark colorings. The final effect is a view made up exclusively of small dark brown rocks spread around the river edge and a river bed made up of small stone and dark think sand. The speed of the river gives it certain transparency in these areas which allows you to observe the fish looking for refuge from the strong currents in between the rocks.
生物群落的水下景观描述：河流流经两岸边缘分布着大型圆形岩石的区域，而在河岸边缘则可见颜色较深的岩石和圆石。整体景象完全由散布在河岸的小型深褐色岩石构成，河床则由小石块和深色细沙组成。河流的流速使这些区域的水体呈现出一定的透明度，让人能够观察到鱼类在岩石间躲避强流的情景。

Description of the parameters of the habitat: I could not find information about the parameters of the habitat.
栖息地参数描述：我未能找到有关该栖息地参数的信息。

Threats to the ecology: The objective of this aquarium is to help create awareness of the contamination of the Guatemalan rivers, being the river Metapa one of the few that is yet to be contaminated but is under threat from the surrounding farms.
生态面临的威胁：本水族箱旨在提高人们对危地马拉河流污染问题的认识。梅塔帕河是少数尚未受到污染的河流之一，但正面临周边农场的威胁。
